How to Wire a Three Way Switch to a Existing Single Pole Light Switch Circuit.

3way-switch

In this video, I explain just how easy it is to add a three-way switch to an existing single pole (one) switch lighting circuit. Now if you are trying to install a completely new 3-way circuit please my video with an article on how to install a three-way.  Otherwise, this may confuse you a little.

Even if you hire an electrician to do the job for you. You can still save a few bucks by installing the wire yourself. I mean that’s the hardest part of this.

The hardest part will be running the 4 wire from the existing switch to the new one. Take a look at my video and ask any questions if you need help.

  1. I have a single switch controlling a lite direct, power source is through the switch, how do I tie the 14/3 I have ran for 2nd switch location to where no need for rerouting the wire to the lite from second switch?

  2. I have a 3way line from switch to light, but only one switch how can I hook the light up to work. Don’t know what to do with the red line
